    Supramammillary nucleus synchronizes with dentate gyrus to regulate spatial memory retrieval through glutamate release

    Yadong Li et al.
    Multi-fiber photometry recording and circuit-based manipulation in vivo identify a long-range SuM-DG circuit linking two highly correlated subcortical regions to regulate spatial memory retrieval through SuM glutamate transmission.

    Hippocampal neural stem cells facilitate access from circulation via apical cytoplasmic processes

    Tamar Licht et al.
    Neural stem cells in the dentate gyrus have unique cytoplasmic processes that promote privileged access to circulating factors by a unique contact point with an endothelial cell.

    Adult-born granule cells mature through two functionally distinct states

    János Brunner et al.
    3-10 weeks old adult-born granule cells provide two temporally overlapping but functionally distinct neuronal cell populations by being sensitive to distinct aspects of their inputs.

    Dendritic spikes in hippocampal granule cells are necessary for long-term potentiation at the perforant path synapse

    Sooyun Kim et al.
    A novel mechanism of local plasticity in the distal dendrites of hippocampal granule cells.

    Hippocampal low-frequency stimulation prevents seizure generation in a mouse model of mesial temporal lobe epilepsy

    Enya Paschen et al.
    Optogenetic and electrical low-frequency stimulation in the sclerotic hippocampus prevents the emergence of spontaneous focal and evoked generalized seizures in a mouse epilepsy model.

    Hippocampome.org: a knowledge base of neuron types in the rodent hippocampus

    Diek W Wheeler et al.
    Hippocampome.org is an online resource that provides free human- and machine-readable access to the comprehensive property-based classification of hippocampal neurons from 14,000 pieces of published experimental evidence.

    Plasticity-dependent, full detonation at hippocampal mossy fiber–CA3 pyramidal neuron synapses

    Nicholas P Vyleta et al.
    Activity-dependent enhancement of transmitter release makes the hippocampal mossy fiber synapse a full detonator in rats.

    Modulation of anxiety and fear via distinct intrahippocampal circuits

    Elif Engin et al.
    The hippocampus features a double dissociation in its circuits with respect to the regulation of fear and anxiety, with CA3 and the dentate gyrus implicated in anxiety and CA1 in fear.

    Parvalbumin interneurons provide spillover to newborn and mature dentate granule cells

    Ryan J Vaden et al.
    Fast-spiking parvalbumin-expressing interneurons generate slow spillover-mediated GABAergic transmission to young adult-born and neighboring mature neurons of the dentate gyrus.
